The most likely cause of the brake lights staying on is the brake light switch. If you follow the brake pedal up under the dash you will see the switch. If you have cruise control then there are 2 switches. If you unplug the first one and the brake lights do not go out, then unplug the second one. There is also a plug that the switch pushes on on the pedal arm. Make sure it's not missing.

The ABS issue may be resolved with this, but might also be a separate issue. So let's get the brake lights working properly first then take it from there.
